# entry.body can be either be TableDumpV1 or TableDumpV2

if not isinstance( entry.body, TableDumpV2 ):
continue # I expect an MRT v2 table dump file

# get a string representation of this prefix
prefix = '%s/%d' %( entry.body.prefix, entry.body.prefixLength )

# get a list of each unique originating ASN for this prefix
originatingASs = set( [
re.split( r'\s+', route.attr.asPath )[-1]

in entry.body.routeEntries] )

# just print it for demonstration purposes
print( '%s -> %s' %( prefix, '/'.join( originatingASs ) ) )
